Nathan is the founder and director of Guardian Project, an award-winning, open-source, mobile security collaborative with millions of users and beneficiaries worldwide. Their most well known app is Orbot, which brings the Tor anonymity and circumvention network to Android devices, and has been installed more than 20 million times. His work on off-grid, decentralized, secure mobile communication networks, dubbed Wind, was originally imagined and workshopped while a fellow at the Berkman-Klein Center at Harvard in 2015. In 2018, Wind was selected as a finalist in the Mozilla-National Science Foundation "Wireless Innovation for a Networked Society (WINS)" Challenges. Guardian Project has worked with WITNESS, the leading human rights media organization, for nearly 15 years on the idea of Smart Cameras solutions that use enhanced metadata, digital signing and notaries, and advanced verification tools to combat mis and dis-information. This work is now realized through ProofMode.org applications and services, and the emerging Coalition for Content Provenance and Authenticity (C2PA) standard providing publishers, creators, and consumers the ability to trace the origin of different types of media.
